Specification of Letters Patent.

Application filed September 7, 1912.

Patented Apr. 14'... 1914. Serial No. 719,087.

To all whom it may concern county, and State of New York, have invented certain new and useful Improve ments in Car-Ventilators, of which the following is a specification.

The invention relates to car ventilators.

One of the objects of the invention is to provide a. car ventilator which can be placed on the roof of a car so as to exhaust theair from the upper interior portion of the latter.

Another object of the invention is to construct a ventilator which will be simple and eflicient and also neat in appearance when on the car.

As showing a specific embodiment of the invention, reference is made to the drawing forming a part of this specification and in which- Figure 1 shows the end view ofan upper portion of a car with the ventilator applied thereto. Fig. 2 shows a partial side view of the upper portion of a car with a ventilator in place thereupon. Fig. 3 is a partial side view and a partial longitudinal sectional view of the ventilator. Fig. 4 is a partial end view and a partial transverse vertical sectional view of the ventilator. Fig. 5is a view looking upwardly toward the under side of the ventilator. Fig. 6-is a plan view of the ventilator, and Fig. 7 is a view taken on the line 77 of Fig. Hooking-in the direction of the arrows. Figs. 5, 6 and 7 are .all shown at'a smaller scale than Figs. 3

and 4 and it will be observed that Fig. 3 is a view taken on the 1ine'3 333, looking in the direction of the arrows (E-08 shown in Fig. 6, and that Fig. 4 is a view taken on the line 41434 looking in the direction of the arrows 4 shown in said Fig. 6.

The ventilator comprises the upright throat or air intake portion 1, the roof port-ion 2 and the air deflecting or suction creating portions 3, 4, 5 and 6. Theuprightthroat portion is hexagonal in cross section and is defined by the upright sides 7 and 8 and the slopes downwardly from end portions 9, 10, 11 and 12. The upright side and end portions of the throatjha've thereupon flanges 13 which provide means whereby the ventilator may be secured in place on the car. The roof is located over the throat portion sides thereof. The roof is preferably substantiallylozenge shaped in plan view and preferably transversely arched so that it the longitudinal center toward the sides.

The deflecting portions 3 and 4 are located at one end of the ventilator-and the.

deflecting portions 5 and 6 are located at the other end of the ventilator, and it will be noted that they extend downwardly from the roof to the throat portion and outwardly from the ends of the ventilator toward the central portion thereof. From an inspection of the drawings it will be observed that the surface elements, in these deflecting portions, which are in a horizontal plane diverge in passing from the end of the ventilator toward the central portion of the sides, and that the surface elements, in said deflecting portions, which lie in a vertical plane approach each other in passing from the roof toward the throat portion.

The side edge 2 of the roof, the deflecting portion 5, the upright side 8 of 'the throat and the deflecting portion 4 define the air delivery openingA at one side of the ventilator, and the side edge 2, the deflecting portion3, the upright side 7 of the throat portion and the deflecting porti6n 6 define the air delivery opening 13 at the other side of the ventilator. Both of these delivery openings A and B are open from the bottom. Each of the deflecting portions is provided with a depending flange (see 3 of Fig. 3; 4 and 6 of Fig. 4). Due to the deflecting portions and the depending flange portions a suction will he created when the ventilator is moved in'a. longitudinal direction, and therefore these deflecting portions and the flanges thereof provide a means for sucking the air from the interior of the car through the throat and causing it to be de livered thro gh the ail discharge openings A and B. I

and extends on opposite It will be observed that the side sections I of the ventilator which are on opposite sides of the centrally located and vertically and longitudinally extending plane MM are symmetrical, and that the end sections on opposite sides of the vertically and transversely extending plane L-L are also symmetrical. I

The improvements herein set forth are not limitedto the precise construction and arrangement shown and described and they may be embodied in various forms and modifications without departing from the spirit and scope of the invention.

WV hat I claim is:'

A ventilator for cars having the side sections on opposite sides of a centrally lo- 'cated vertically and longitudinally extend ing planesymmetrical and having the end sections on opposite sides of a vertical and transversely extending plane also symmetrical, said ventilator having an intake opening at the bottom, an upright throatportion which is hexagonal in cross section, a substantially lozenge shaped roof transversely arched and end portions having outer surfaces whose surface elements which lie in a horizontal plane extend outwardly in passing from the end of the ventilator toward the centrally located transverse plane above referred to, and whose surface elements which lie in a vertical plane approach each other in a downwardly direction, the roof, ends and sides of the vertically extending throat portion formingthe air suction and I delivering means and defining the air delivering openings which are open from below and which are located at the under sidesof the ventilator on opposite sides of the longitudinally and vertically extending central planeabove referred to.

2. A ventilator for railway cars having a throat portion providing an intake opening at the lower central portion of the ventilator, a roof which extends over the throat portion on opposite sides thereof, and two.

portions at each end of the ventilator, said portions having surfaces that dii'erge'in passing from the end of the ventilator toward the-central portion of the ventilator and which converge inv passing from the roof of the ventilator toward the .bo'ttonr portion thereof, said deflecting portions having therebetween the air delivery means of the ventilator which terminates in the air delivery opening at the under side of the ventilator.

3. In a ventilator for railway cars the combination of a vertically extending throat hexagonal in cross section, securing flanges thereupon, a substantiallv lozenge shaped roof and walls or portions which extend inwardly and downwardly from the roof to the throat portion and outwardly in passing from the end of the ventilator toward the central portion thereof, said deflecting portion at each side of the ventilator having therebetween the air delivery opening. 7 4. In a ventilator for railway cars the combination of a vertically extending throat hexagonal in cross section, securing flanges thereupon, -a substantiallylozenge shaped roof and walls or portions which extend inwardly and downwardly from the roof to the throat portion and outwardly in passing. from the end of the ventilator toward the central portion thereof, said deflecting portion at each side of the ventilator having therebetween the air delivery opening, said deflecting portions at each side of the ventilator being provided with depending lips or flanges- 5.
